Multicenter Study
Association of sugammadex reversal of neuromuscular block and postoperative length of stay in the ambulatory care facility: a multicentre hospital registry study.
Encapsulation of rocuronium or vecuronium with sugammadex can reverse neuromuscular block faster than neostigmine reversal. This pharmacodynamic profile might facilitate patient discharge after ambulatory surgery. ⋯ Reversal with sugammadex compared with neostigmine was associated with a small decrease in postoperative length of stay in the ambulatory care unit. The effect was magnified in older and high-risk patients, and can be explained by reduced postoperative nausea and vomiting. Sugammadex reversal in ambulatory surgery may also help reduce cost of care.

Observational Study
Endotypes of intraoperative hypotension during major abdominal surgery: a retrospective machine learning analysis of an observational cohort study.
Intraoperative hypotension is associated with myocardial injury, acute kidney injury, and death. In routine practice, specific causes of intraoperative hypotension are often unclear. A more detailed understanding of underlying haemodynamic alterations of intraoperative hypotension may identify specific treatments. We thus aimed to use machine learning - specifically, hierarchical clustering - to identify underlying haemodynamic alterations causing intraoperative hypotension in major abdominal surgery patients. Specifically, we tested the hypothesis that there are distinct endotypes of intraoperative hypotension, which may help refine therapeutic interventions. ⋯ Hierarchical clustering identified six endotypes of intraoperative hypotension. If validated, considering these intraoperative hypotension endotypes may enable causal treatment of intraoperative hypotension.

The randomised controlled trial is the foundation of clinical research; yet there is concern that many trials have flaws in design, conduct, and reporting that undermine trustworthiness. Common flaws in trials include high risk of bias, small size, outcomes irrelevant to clinical care and patient's experience, and inability to detect efficacy even if present. These flaws carry forward into systematic reviews, which can confer the label of 'high-quality evidence' on inadequate data. ⋯ Some trials have been discovered to be fabricated, the number of which is growing. The fields of anaesthesia and pain have more fabricated trials than other clinical fields, possibly because of increased vigilance. This narrative review examines these themes in depth whilst acknowledging an inescapable conclusion: that much of our clinical evidence is in trouble, and special measures are needed to bolster quality and confidence.

Randomized Controlled Trial
Hypnosis as an alternative to general anaesthesia for paediatric superficial surgery: a randomised controlled trial.
Reducing perioperative anxiety and controlling pain in children are essential to optimise recovery and outcomes for both children and their parents. By acting on sensory and affective modulation of anxiety and pain, hypnosis is widely used in medical care, especially in anaesthesia. This randomised controlled clinical trial was designed to compare general anaesthesia and intraoperative hypnosis support for perioperative management of children undergoing superficial surgery. ⋯ NCT02505880.
